Reorder `DumpSection` under `handleArgs` in file `ELFObjcopy.cpp`.
`DumpSection` is placed before `replaceAndRemoveSections` and is
therefore now the first operation under `handleArgs`. Thus, it is now
performed before both `add` and `remove` section operations.
Change for the MachO format at D81123. Together fixes https://bugs.llvm.org/show_bug.cgi?id=44283.
